Extralite's straight pull front road hub design, the SPM, is their lightest at 47 grams. The drillings have been moved out on each side, resulting in increased lateral stiffness of the complete wheel.
The UltraFront SPM hub flanges are specially heat treated to handle the stresses of radial spoke lacing, while the axle ends are specially hard-anodized for long wear life.
100% made in Italy.
As with all Extralite products, UltraHubs exceed the European UNI/DIN Safety standards. Extralite's safety tests simulate a very strong 90kg (200lb) rider output.
We recommend that Extralite hubs, especially the SPM be built by an experienced wheelbuilder. We are happy to provide this service, and can provide helpful suggestions in rim and spoke selections. Please contact us directly or submit a form for a custom wheelbuild here.
